Hi.<br>
I am using declared types in .drl rule rule. When I kept the number of<br>
fields in a declared type low, drools works fine. When I am increasing the<br>
number of fields in a declared type to 300 or even more, drools raising an<br>
exception.<br>
Particularly, it is giving this.<br>

I suspect, it is something to do with creating class, constructor with so<br>
many arguments at run time. I am looking for a solution, something like<br>
declared types, or a workaround. The purpose for which I am using Drools<br>
limits to use the traditional Java classes, or defining a Java class.<br>
Also, is there any way, to perform calculations, or value propagations.<br>
That, Drools could assume some value to a variable given a certain<br>
constraint on it.<br>
<br>
For example, x > 6 && x < 9, Drools could assume x as 7 or 8 and fire rules?<br>
<br>
Thank you.<br>
